Ternary rare earth luminescence complexes composed of Tb (III)-phthalic acid (H2L)-1,10-phenanthroline (phen) were synthesized using precipitation method. The elemental analysis, plasma atomic emission spectra, infrared spectra were measured the composition of obtained samples and the chemical composition deduced is TbL3/2(phen)0.5. XRD patterns show that the obtained coordination compound is new crystal different from that of two ligands. SEM results indicate that the coordination compound is a floral crystal with the size about 1-2 µm and has better dispersity. The TG-DTA result showed that the luminescence complex has good stability below 478 oC. Photoluminescence analysis indicated that the coordination compound emits Tb3+ characteristic green luminescence under ultraviolet excitation.
